Extract shards

# Extract to custom directory
python TurnMaster_processing/extract_shards.py --sharded-dir ./ --output-dir Turnmaster_raw

OPTIONAL: remove shards

Remove extracted shards (unecessary for the latter pre-processing)
rm -rf audio/

OPTIONAL: create a curated version of the dataset. You can also skip this step and reuse the standart curated version of TurnMaster

# Extract from cached download
python extract_shards.py --sharded-dir ~/.cache/huggingface/hub/datasets--turnmaster--TurnMaster/snapshots/main --output-dir extracted
